Djed Stablecoin Cardano’s Verified Algorithmic Solution
Djed is an advanced algorithmic stablecoin developed by Input Output Global (IOG) and powered by COTI. Designed to function like an autonomous bank, Djed maintains its value through a system that buys and sells stablecoins within a specific price range. It is backed by ADA, Cardano's native cryptocurrency, and supported by SHEN reserve coins to ensure stability. The protocol stands out for its rigorous approach to stability, with its claims formally verified using mathematical proofs. This verification is achieved through two main techniques: bounded model checking and interactive theorem proving. By over-collateralizing its reserves with a ratio ranging between 400% and 800%, Djed effectively manages market volatility and maintains a stable value for its users. This innovative system combines algorithmic control with formal verification, setting a new benchmark for stablecoin reliability and security.
Client Requirements
The primary requirement for the Djed stablecoin was to establish a reliable system that maintains price stability in volatile markets.

This high reserve ratio provides a cushion against market volatility, reducing the risk of instability and ensuring that Djed remains reliably pegged to its target price. The over-collateralization strategy enhances the stability and security of the stablecoin.
Formal Verification
Djed's stability claims are rigorously verified using formal methods. This includes bounded model checking, which exhaustively searches for counter-examples to the stability claims, and interactive theorem proving, which constructs formal proofs of the claims. These verification techniques ensure that the stability mechanisms of Djed are mathematically sound and reliable. Formal verification builds trust in the protocol by providing robust evidence that the stability claims are accurate and that the system operates as intended.
Dynamic Pricing
The Djed protocol features a dynamic pricing mechanism that adjusts buy and sell prices based on market conditions. This feature helps to stabilize the value of the stablecoin by managing supply and demand effectively. When market conditions change, the protocol automatically updates the prices to maintain the target peg, ensuring that the stablecoin remains stable and reliable. This dynamic pricing approach is essential for preserving the stablecoin’s value in fluctuating markets.
Mint and Burn Mechanism
Djed employs a mint and burn mechanism to regulate the supply of stablecoins.

Consensus Mechanism
Automated Price Adjustment
The protocol employs automated price adjustment algorithms to regulate the buying and selling prices of Djed. These algorithms respond to market conditions in real-time, adjusting the prices to maintain stability. When the stablecoin’s price deviates from its target, the system automatically updates the buy and sell prices to bring the value back within the desired range. Automated price adjustments are essential for preserving the stability and usability of Djed in a dynamic market environment.
Dynamic Reserve Adjustments
Djed uses a dynamic reserve adjustment mechanism to maintain its stability. The protocol continuously monitors market conditions and adjusts the reserve levels and collateral ratios accordingly. By dynamically managing the reserves, Djed can absorb fluctuations and maintain its target price. This mechanism ensures that the stablecoin remains reliably pegged, even during periods of high market volatility, by adjusting the reserve to reflect changes in supply and demand.
Reserve Coin Trading
The protocol utilizes reserve coin trading as a consensus mechanism to support its stability. SHEN reserve coins are actively traded to manage the reserve levels and maintain the required collateral ratio. This trading activity helps to capitalize the reserve and ensure that it remains significantly higher than the issued stablecoins. By actively managing reserve coin trading, Djed enhances its stability and supports the overall effectiveness of the stablecoin system.
Proof of Stake (PoS)
Djed leverages Cardano’s Proof of Stake (PoS) consensus mechanism, where validators are selected to create new blocks and validate transactions based on the amount of ADA they stake. This mechanism ensures that participants have a financial interest in maintaining the network’s integrity, as they are incentivized to act honestly to protect their staked assets. PoS is energy-efficient compared to Proof of Work and enhances network security by requiring validators to lock up ADA as collateral, which is crucial for maintaining the stability and reliability of Djed.
On-Chain Data Verification
Djed utilizes on-chain data verification to ensure transparency and accuracy in its operations. The protocol provides real-time access to data related to prices, supply, and reserve ratios directly on the blockchain. This approach allows users and stakeholders to independently verify the stability and backing of the stablecoin. On-chain data verification supports trust in the protocol by ensuring that all relevant information is readily available and transparent, contributing to the overall credibility of Djed.
Smart Contracts
Smart Contracts Development are employed to automate various functions within the Djed protocol, including minting and burning stablecoins. These self-executing contracts operate based on predefined rules and conditions, ensuring that transactions and adjustments are executed without manual intervention. By using smart contracts, Djed can efficiently manage the supply of stablecoins and enforce the protocol’s rules, enhancing the stability and reliability of the system while minimizing human error.
Governance Mechanism
Djed incorporates a governance mechanism that allows stakeholders to participate in decision-making processes. This mechanism enables the community and key stakeholders to propose and vote on changes to the protocol, ensuring that the system evolves in response to emerging needs and challenges. Governance mechanisms provide a structured approach to managing and updating the protocol, ensuring that it remains effective and relevant over time.

Challenges
Ensuring Stability Amid Market Volatility
One of the primary challenges in developing Djed was maintaining price stability in the face of market volatility. The cryptocurrency market is known for its dramatic price swings, which can significantly impact the value of stablecoins. To address this, Djed implemented an over-collateralization strategy with a reserve ratio between 400% and 800%. This means that the collateral backing Djed is significantly higher than the value of the stablecoins issued, providing a buffer against market fluctuations. Additionally, the protocol employs dynamic reserve adjustments and automated price adjustments to manage supply and demand effectively. Despite these measures, ensuring consistent stability requires continuous monitoring and rapid adjustments to respond to sudden market changes. The team had to design a robust mechanism capable of absorbing shocks while keeping the stablecoin's value within the desired range.
Formal Verification of Stability Claims
Another significant challenge was the formal verification of the stability claims made by Djed. The protocol needed to ensure that its stability mechanisms were not only theoretically sound but also practically reliable. This involved applying formal verification techniques such as bounded model checking and interactive theorem proving. Bounded model checking exhaustively searches for counter-examples to stability claims, while interactive theorem proving builds rigorous formal proofs. Both methods are complex and require thorough testing and validation to ensure that the protocol performs as intended under various scenarios. The challenge was to develop a verification process that could accurately confirm the protocol's claims and address any potential issues identified during testing.
Maintaining Transparency and User Trust
Ensuring transparency and building user trust posed a third challenge for the Djed project. For a stablecoin to gain widespread acceptance, users need to have confidence in its stability and backing. Djed addressed this challenge by providing real-time access to data on prices, supply, and reserve ratios through its platform. However, maintaining transparency requires not only accurate data reporting but also clear communication of the protocol’s mechanisms and updates. The team had to ensure that users could easily access and understand the information needed to verify the stablecoin's stability and security. Balancing technical complexity with user-friendly interfaces and effective communication was essential to foster trust and confidence in the Djed protocol.
